Title: Semiconductor device and its preparation
Inventor: KAWAHARA HIROYUKI
IPC: H01L21/3205
Filed: 1990-09-03
Abstract: PURPOSE:To realize a semiconductor device having low contact resistance and high reliability using conventional materials and technologies by forming the contact section between the electrode wiring layer and the semiconductor substrate into a channel shape. CONSTITUTION:Channel type contact surface 5 is formed in the connecting hole of semiconductor film 2 on a p-type silicon substrate 100. the second n-type semiconductor layer 6 is formed by implanting ions after forming the channel type contact surface 5 in the p-type silicon substrate 100. Wiring metal layer 3 is made, as an example, of Al-1%, Si-0.5%, Cu, and is in contact with the first and the second n-type semiconductor layers 1 and 6. As aforementioned, since the contact between the first and the second n-type semiconductor layers 1 and 6 and the wiring metal layer 3 is carried out not only on the channel bottom surface but also on the side surface of the channel, the contact area increases, thereby reducing the contact resistance.

Title: Motive power transmission belt for continuously variable transmission mechanism
Inventor: FUKUOKA TATSUHIKO
IPC: F16G5/16
Filed: 1983-12-13
Abstract: PURPOSE:To make the efficiency of transmission high and nearly constant from the low region of transmission ratio to the high region thereof, by selectively sulfurizing the iron of a steel block except for its surfaces which come into contact with rotary members. CONSTITUTION:In a motive power transmission belt comprising a steel belt portion 18 and steel blocks 10, the iron of each steel block is selectively sulfurized except for its surfaces which come into contact with rotary members 1a, 1b.

Title: Balloon type expansion antenna for mounting satellite
Inventor: YOKOTA TOYOHACHI
IPC: H01Q1/28
Filed: 1993-08-26
Abstract: PURPOSE:To adopt the parabolic surface of a free shape and to eliminate the influence of heat distortion by sunlight by obtaining a balloon formed by a material provided with two characteristics of radio wave transmission and sunlight reflection. CONSTITUTION:The parabolic surface 2 is formed by adding radio wave reflection characteristics to the foldable or rollable and expandable material such as a film or a mesh or the like. Thus, the surface 2 can be housed small until the balloon 1 is expanded in an outer space and can be expanded and used at required time. Since the surface 2 can be installed inside the wide space of a center part independently from the balloon 1, the shape of the surface 2 can be free. Since the position of the balloon 1 of the surface 2 is near a center, the influence of not only the irradiation of the sunlight but also the surface heat of the balloon 1 is not received. A feeder part 3 is installed at the focus position of the surface 2. The surface 2 and the feeder part 3 are fixed to the prescribed position of the balloon 1 by a holding part 4 and the surface 2 can be made round and small until it is expanded. Thus, without shaping the balloon 1, the surface 2 can be in the free shape and the influence of the heat distortion of sunlight irradiation can be eliminated.

Abstract: PURPOSE:To improve the processing speed of an electronic computer by starting the execution of an instruction although the instruction length is insufficient during execution of the instruction and loading the instruction to a buffer register from a main memory when necessary. CONSTITUTION:The data is sent every 4 bytes from a main memory 1, and therefore the 4-byte data is supplied to registers IBF0 and IBF1 in the next cycle. In this case, no instruction is loaded to an I-register from a buffer register 2.

Title: Amplifier
Inventor: MIKAMURA YASUKI
IPC: H03F3/08
Filed: 1989-09-11
Abstract: PURPOSE:To prevent the reduction in an output voltage by using an integration circuit so as to detect the excess of the input current of a transimpedance type amplifier over a prescribed value and to form a shunt of the input current. CONSTITUTION:Since an integration circuit 101 integrates an output signal of an amplifier 2, when an input optical current iPD is increased, an output voltage Vout of the amplifier 2 is decreased and an output current voltage of the integration circuit 101 is decreased. Since a prescribed voltage VG is given to a gate of a FETQ5, a gate-source voltage is increased as an optical signal made incident in a photo diode 1 is larger. Thus, the FETQ5 is conductive when the average value of the light power made incident on the photodiode 1 exceeds a prescribed value by selecting properly a threshold voltage of the FETQ5 to a value and a shunt of the input optical current iPD is formed.
